UE56-1_PGM Undulator PGM fs variable polarisation

Soft x-ray beamline for flexible end stations with vertical horizontal and elliptical polarization covering the range of ~100 - 1400 eV with an x-ray spot size of approximately 80 µm (horizontal). This beamline is part of FemtoSpeX which allows to perform femtosecond time-resolved experiments using the slicing facility. One can also do picosecond measurements using the high resolution (1200l/mm) grating. The ump laser system can run at up to 6kHz but also at reduced repetition rates of 3kHz and 1.5kHz. The system is delivering 800nm laser pulses of about 100fs length with a power of up to ~10W. For 800nm and the 2nd harmonic, i.e. 400nm, variabel attentuation and polarisation is available. For the tunable wavlengths created by the OPA we can currently only offer fixed attenuations by using ND filters.
